The Coolant Temperature Sensor or ECT sensor for the gauge is in the drivers side cylinder head between the front two spark plugs. Use care and allow enough time for the engine to cool before removing the ETC sensor. You will need to refill the cooling system. Bellow a picture from a repair manual http://bit.ly/40yBqj
